<li>Now we'll make the new device a '''physical volume''', add it to the '''volume group'''by issuing the following commands: <code>pvcreate /dev/vdb1</code> (enter '''y''' to proceed - ignore warning) <code>vgextend centos_centos2 /dev/vdb1</code></li>

<li>Re-issue the '''ssm list''' command to see if there is any change.</li>

~~</ol>~~

~~ ~~

:'''NOTE:''' There is a problem extending the home logical volume because we logged in as a regular user (prior to logging in as root), thus the /home directory cannot be unmounted in order to extend the logical volume for centos_centos2/home. We can get around this problem by changing our '''run level to 1 (single-user mode)''' and unmount the '''/home''' partition.

~~<ol>~~

~~<li value="10">Issue the following command as root to change the run-level to 1 (single-user mode): <code>init 1</code></li>~~

~~<li>Enter your root password</li>~~

~~<li>Issue the following command to unmount the /home partition: <code>umount /home</code></li>~~

<li>Issue the following command to extend the logical volume for the home file-system: <code>lvextend centos_centos2/home --size +2G</code></li>

<li>Record the size of the volume group and the amount of free space. What has changed and what caused those changes?</li>
